Description
MD (metrodisplay) is a big LED matrix assembly with game controls to play pong and tetris (in progress). It's built with four outdoor (very bright) P5 64x32 panels, a custom pcb with an esp32, a cnc'd wooden frame, and power distribution from mains AC. The total cost of the project is under $90 USD.
I was originally making a small project with a single LED panel to display subway times for the Vancouver Skytrain (hence the name), but I realized that while that was great for a static bedroom display, something much more exciting and interactive like this would be much more fun to showcase at Opensauce!

Questions
How big is the Metrodisplay PCB?
It measures 99.3 × 52.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Metrodisplay use?
56 parts, built around the SN74AHCT245PWRE4, ESP32-DEVKITC-VE and RVT470UF35V67RV0056. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Metrodisplay KiCad files?
From the vuktacic/metrodisplay repository on GitHub, at the commit this page was made from: the board is pcb/metrodisplay.kicad_pcb and its schematic pcb/acpower.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Metrodisplay design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
